1. Pikes are associated with death in the Finnish mythology. It was believed that they could swim between the worlds of the living and the dead. However, if a pike was asked to take a soul to the underworld while the person was still alive, it might cause them to get critically ill. Basically that was one way to curse a person.

2. Wolf and dog were common ways to call a pike because of its appearance and behaviour.

3. A pike gave fire to the humans in some stories. A fire fell from the sky, and a small fish swallowed it, then a bigger fish ate that fish, and finally a pike ate the bigger fish. Then humans captured the pike and managed to get the fire from the fishes' stomach.

4. Sometimes a dead person could end up in a pike's bowel (which may have been a part of the underworld) for some reason. That was really bad, because the soul was then stuck there, and couldn't be contacted in any way anymore. Even a seer (or 'a wise man') couldn't get anyone out of there and was in danger of getting stuck there, too, if he tried to contact a soul there.
